Passes control to the operating system, specifically DOS/Windows 3.x, so it can process events. After the operating system finishes, you regain control.
If you do not want your C/AL code to completely tie up the system for long periods of time, you can insert this function periodically so other programs can run. For example, if you are creating a report which needs to read many records, you may want to occasionally use this function so other users can continue to work.
This function is not supported in the RoleTailored client.
